The system administrator wants to use a new jfslog /dev/fs1log with the filesystem /test/fs1 on the testvg volume group. The following commands were used to create the log and assign it to the filesystem： （1）mklv -t jfslog -y /dev/fs1log testvg 1 （2）chfs -a log=/dev/fs1log /test/fs1 While trying to mount the /test/fs1 filesystem the administrator received the error： "Cannot mount /dev/fs1lv on /test/fs1： A system call received a parameter that is not valid". What step did the administrator miss that most likely caused the error？（）A、Use the logform command to format /dev/fs1log as a jfslogB、Use the chlv command to change the lv type of /dev/fs1log to jfslogC、Use the chvg command to change the default jfslog of testvg to /dev/fs1logD、Edit the /etc/filesystems file to change the log associated with /test/fs1 to /dev/fs1log
